DEVICE FOR TREATING FOODS.

Original No. 1,502,409, dated July 22, 1924, Serial No. 561,075, filed May 15, 1922. Application for reissue filed .Tune 16, 1926.

The object of this invention is to provide an apparatus for treating foods, more par,- ticularly the extracting of salt from pickled foods or the neutralizing thereof, and also for the washing and cleaning of foods from dirt or other foreign matter.

The complete neutralizing of large quantities of pickled meat, fish and the like has hitherto not been possible, and the-processes which have become known up tothe present` are accompanied by a series of-wants and disadvantages which shall be removed by the invention,

Meat, fish and the like which in order to preserve them had been strongly pickled were hitherto best neutralized by placing them into flowing water. In suchcase the goods were contained in receptacles which gave the water an' easy access to the goods and which also allowed the Water to quickly flow off again. The water in this case lixiviated the salt conta-ined in the goods. This process had vhowever the disadvantage that also in case of a long action of thefwater only the outer parts directly affected by the water became to a certain extent neutralized kept its whole amount of salt. Forzcertain goods, for instance, .for such which are usedl for the manufacture of fish meal it is abso-= lutely essential to'remove the amount of salt4 contained as far as possible without at the same time allowing that lossesof nutrition occur. The neutralizing could .be achieved by exposing very small. quantities tothe influence of flowing water.l The carrying out of such a process is, however, on the whole not possible in .view ofthe large quantities which have to be handled.r In many-.cases also thekind-of the goods-to: be neutralized forbids the using of such af process. .This process has still. .further the disadvantage that in case of a large content ofsalt the neutralizing will last from 24 to 48 hours and that alreadyv inl case of a twenty-'four hour treatment the goods in consequence of thelixiviation of albumen lose at least -10.%'

of their nutriton..-1.=.-.It has been: ascertained able for being fed out alone.

serial No. 116,474.

from experiments that when treating large quantities of goods, 'the nutrition of the goods is considerably decreased in consequence of the treatment with Water without the contents of salt being drawn of? to the desired extent.

If the water used for the treatment is not of a low temperature, that is to say of about from -1D degrees centigrade, but of a higher temperature, the goods perish` very easily after a treatment of a long duration.

All these disadvantages are according'to the present invention removedI by bringing the materials to be neutralized into a receptacle and after having filled the latter .with water subjecting the materials to the action of an agitating device, during the agitating fresh water being admitted at the upper endwhile at the bottom end of the receptacle the salt-containing water is Alet ofi.

With the aid of this process it is possible in about from 1% of an' hour up to 2 hours to carry through a thorough neutralizing of the goods without an appreciable loss of nutrition occurring. The latter does not quite amount to 1%. The new process makes it possible to use the strongly pickled ofals of the fish industry and other pickled raw materials for the manufacture of iisli meal. Heretofore the raw materials for the reasons mentioned in the aforegoing had to be worked upwith a full content of salt, i. e., with4 about from #20%. The fodder obtained therefrom were, however, in consequence of its high vcontents of salt unsuit- They could only bevused in very small quantities as an addition to the otherwise used fodder. It must be taken into consideration that for instance a pig can stand-.3% of saltin the fodder only for a short period; longer feed- .ing periods with fodder of the content-of salt mentioned" usually cause the Vdeath of the animal. l

By means'A of the new process it is possible toneutralize in :the -shortest time; in one 'working operation quantities of from 2000- l3000 kg. of raw material according to the size of theV receiving, vessel, the quantityfof water admitted and to the amount of. power available. l

It is often found dicult in washing such foods as vspinach and other .leafy plants, to

thoroughly. clean these foods owing to the clustering-ofthe leaves and Vthe..irregular .tra

surface presented; -by them,A 'evenf where/nain- 1 ningv Water is in contactWi-th :thempand 1t 1sfound by the use ot my impro-ved device that such foodsmaybe readily washedand.,
